I am very sorry that this addon is not continued any longer!!!

I tried the bugfix mentioned by homatata but without success. Is there a nother way to get this addon running? Or a way to pay the author for updates?

Best regards!

btw. In order to edit the xpi-file you can open this archive with 7zip and than open/edit the rdf file directly out of the 7zip window.
